Question

How do I determine the closest AWS Region to my users programmatically?

Answer 1

Example code using AWS SDK for JavaScript (Node.js):

const AWS = require('aws-sdk');
const { promisify } = require('util');

const ec2 = new AWS.EC2();
const describeRegionsAsync = promisify(ec2.describeRegions).bind(ec2);

async function getClosestRegion() {
    const regions = await describeRegionsAsync({});
    // Implement logic to determine closest region based on user's location
    return closestRegion;
}

getClosestRegion().then(console.log).catch(console.error);
